In this fun center activity, students will sort mixed addition and subtraction facts according to whether the sums and difference are true or false! I used these as a pocket chart center with my 2nd graders and they loved every minute of it! The June file includes mixed addition to +9 and subtraction facts to -9. Offers both a color and black and white version. Clipart for June features a cute bumblebee. Includes recording sheet. Save $5 if you purchase the year-round bundle!
